COASTER BRAKE.

Application filed March 10, 1922. Serial No. 542,792.

Be it known that I, NICHOLAS. WV.

BAECHLE, a citizen of the United States, and

a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in coaster wagons and the like.

.. brake The objects of my invention are to provide a means whereby the rider can bring the coaster to a stop without removing his or her hands from the steering mechanism.

Another object of my invention is to provide a means whereby the back rest can be so adjusted in relation to the steering mechanism as to accommodate different size occupants.

Another object of my invention is to provide a means whereby the brake or brakes can be applied to the wheels by the back.

Another object of my invention. is to provide a means whereby the brake arrangement is applied to the ground by a slight pressure backwards on the back rest by the rider.

Another object of my invention is to provide a means whereby the brake or brakes 'can be applied to the wheels or to the ground.

My invention consists in the novel combination and arrangement of parts and in the details of construction as herein set forth and claimed.

In the drawings: 7

Fig. 1 is a side elevation of the brake, that is applied to the" ground, mounted in a coaster wagon;

Fig. 2 is aplan view thereof;

Fig. 3 is a rear elevation of Fig. 1;

Fig. 4 is a bottom view of Fig. 2;

Fig. 5 is a sectional elevation of the that is applied to the wheels and is taken on a'plane corresponding to the line 5-5 of Fig. 6; I

Fig. 6 is a rear elevation of Fig. 5 with parts broken away; and

Fig. 7 is a. perspective view of the brake mechanism in which the brakes engage the wheels.

In the embodiment of my invention as illustrated and which shows a perferred con struction, I provide a coaster provided with a body 1. Back rest 2 is rigidly fixed to supporting members 3 and 4 by screws '5 and 6 or other suitable means of construction. The body 1 is provided with slots 7 and 8 for the purpose of receiving sup porting members 3 and 1 respectively. 'A V U shaped bracket 9 forming aback rest mounting is substantially fixed to the urn der side, of body 1 by bolts 10 and 11 and is centrally located between slots 7 and 8,

said bracket ,forming'a pivot means for supporting. members 3 and 4.

The lower ends of supporting members 3 and 4 have a shaft 12 rigidly connected therebetween' on which roller 13 oscillates.

Brake mounting leis bolted to underside of coaster 1 by bolts 15 and'16 and has brake 17 pivotally attached thereto by hinge 18. i

Brake 17 is of wood or other suitable material and extends rearwardly and downwardly from brake mountingl l and its lower end is faced or covered with a metal shield 20.

The upper rest stop 21 substantially fixed thereon which engages roller 13 thus limiting the forward movement of back rest 2; The reversed movement of back rest 2 or when rider leans against it is limited, when Spring 23 is attached to the lower sideof coaster body 1 and the upper side of brake 17 by spring eyes 24 said eyes being embedded in the respective parts; Holes 25.

26, 27 and 28 respectively to the front of coaster 1 are for the adjustment of bolts 15 and 16. Holes 25, 26', 27 and 28 re spectively to the rear part of coaster 1 are for the adjustment of bolts 10 and 11.

The normal position of this style, is shown in Fig. 1 by full lines, and the engaging or braking position is represented by dotted lines. To operate this brake the ri'derfwho is seated on body 1 merely applies pressure to back rest 2, this pressure overcoming spring'23 and permitting roller 13 to ride forward on back rest stop 21 thereby depressing brake 17 until metal shield 20 "comes in contact with the ground thus stopping the coaster as desired. \Vhen the pressure side of brake 17 has a back through axle 50, or support .thereon said i is released the spring 23 automatically draws brake 17 upward and roller 13 backward, until said roller engages back rest stop 21 thus limiting forward movement of back rest 2 and holding the brake in a disengaged position.

I Figs. 5, 6 and 7 illustrate a modified construction of my invention wherein a pivoted shaft 29 oscillates in the ends of support members. 3 and 4. On the under side and to the rear. of coaster l bracket 30 is rigidly attached. Bracket 80 has downwardly projectingears 31 and 32 formed at each end thereof- Ears 31 and 32 act as apivot support for one end of brake supporting links 33 and- 34. The upper ends of said brake supporting links are provided with grooves 35 and 36 for the purpose of receiving ears 44 has internal threads 47 adapted to hold encircles Sland 32 and are pivotally held in place by cotter pins 37 and 38. The lower ends of said brake supporting links are providedwith holes 39 and 40 through which brake shoe rod 41 passes and is rigidly attachedthereto. Brake'shoe rod. 41 has brake'shoes 42 and 43 securely attached to its ends. T

shaped connecting member 44 is centrally located between links 38 and 34 and the I portion 45 (as indicated in Fig. 7 pivotally receives brake shoe shaft 41. The front portion 46 of T shaped connecting member one end of shaft 48; Coil spring. 49 shaft 48 and is seated at one end on front portion 46 of T shaped connecting member 44. Shaft 48 passes axle forming the other seat for coil spring ss: 49. Shaft 48 is slidably extended through axle 50 and spacing sleeve 51 thence through square shaft 29' and is held in place by adjusting nut 52.

.Adiusting nut, 52 is for the purpose of limitlng the movement of the back rest and of taking up wear of. the brake shoe.

Back rest 2 onthis style brake is limited as to its forward movement by spacing sleeve 51. I

While I have shown and described particular, constructions. asset forth it will be apparent that my invention is capable of modification without departure from its scopeor spirit as defined in the claims.

4 WhatI claim as new and desire to secure I by Letters-Patent is;

. V 1. In coaster brakes, a pivotally mounted back rest and a brake operated thereby, whereby movement of the back restfwill operate said brake.

2. In coaster brakes, a coaster, a back rest pivotallymounted thereon and a brake pivota-lly connected to said coaster and slidably engaging said back rest.

3. In a coaster brake, a coaster, a back 'restpivotally mountedthereon, a brake pivotally attached to said coaster and slidably pivotally mounted thereunder, a brake.

mounting, a brake hinged thereto'and extending downwardly and backwardly there from, a stop on said brake, a shaft connecting said sup-ports, a roller on said shaft adapted to oscillate inengagement with said to hold saidstop and a spring adapted brake in non-braking position. 6 ..In a coaster brake, a coaster, a back restplvotally mounted thereon, abrake pivotally mounted and hav ng a bearing face thereon, a stopon said brake,fandmeans for engaging said back restand stop.

7. In a coaster brake, a coaster, a pivot- I ally mounted back rest, a roller mounted on a the lower end thereof, a. pivotally mounted gagement with each other..

8. In a coaster brake, a coaster having steering means and provided with slots, through; its seat portion, supports for said back rest extending through said slotsand pivotally; mounted; thereunder, a brake mounting, a brakehinged thereto andextending downwardly and; backwardly therefrom, a stop on said brake, a shaft connecting said supports and adapted to have s1id-' ing engagement with said stop, and a spring adapted tohold said brake in non.

braking position.

9. In a coaster brake, a coaster having slots in itsv body and provided with suitable steering means, a U-shaped bracket mounted thereunder between said slots,,.;a .backrest,

supports for. said back rest" extending through said slots and pivotally connected 05' brake,a stop on said. brake and a spring 1 adapted to hold said roller and brake in en-.

to said U-shaped bracket, a; shaft'con-nectingthelower ends of' said support, a pivotally mounted brake having a suitable bearing surface, a stop on .said' brake, shoe adapted to engage said shaft and limit the forward movement of said back rest and a spring connected to said body and to said brake shoe. whereby said brake shoe is automatically held in engagement with saidshaft and automatically returned to 110115 braking position when from said back rest.
